Explanation:
The total energy of the system remains conserved. It just converts from one form of energy to another.
The battery of the cell phone contains chemicals. As the electricity is passed through the cell phone, the electrical energy is converted to chemical energy. As she notices that the phone is warm and after the battery has been fully charged and the student unplugs her cell phone, the phone vibrates when a message arrives, this shows the conversion of chemical energy to mechanical energy, thermal energy etc.
Hence, we can say that the correct option is (b).
If you divide 68.5 km/h by 60 (the minutes in an hour) and then you get 1.141 then you multiply it by 5.45 and you get 6.222!
Your Answer is 6.222!!!!
The plastic jars of the air capacitor represent the parallel conducting plates.
<h3>What is Air capacitor?</h3>
Air capacitor is a type of capacitor that uses air as its dielectric. The simplest air capacitors will contain two conductive plates separated by an air gap.
This capacitor stores and releases electricity in the circuit using;
- air as the electrical source,
- balloon as the insulator and
- the plastic jar as the parallel conducting plates.
Thus, the plastic jars of the air capacitor represent the parallel conducting plates.
